DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair dye composition which is excellent in dyeing property and fastness and has a good feel after hair dyeing.

[0002]

2. Description of the Related Art Conventionally, hair dye compositions for hair have been
An oxidation hair dye that dyes hair using an oxidation-reduction reaction using an oxidation dye such as a p-phenylenediamine compound, and an acid hair dye that dyes hair in an acidic region using an acid dye. is there. Among them, the acid hair dye, an acid dye, for example, benzyl alcohol, a hair dye accelerator such as N-methylpyrrolidone, and a thickener such as hydroxyethyl cellulose, for example, is blended, for example, an acid such as citric acid, or The pH was adjusted to 1.5 to 4.5 with a salt of those acids, such as sodium citrate. However, since such acid hair dyes do not have sufficient dyeing properties and fastness, it has been proposed to use a hair dye accelerator together with an acid dye for the purpose of solving the problems.
There have been many publications such as Japanese Patent Publication No. 1 and Japanese Patent Application Laid-Open No. 62-164612.

[0003]

However, since such an acidic hair dye contains a large amount of a hair dye accelerating agent, there is a problem that the hair treated with the hair dye becomes rough.
Therefore, the present invention improves such disadvantages of the conventional acidic hair dye, and provides a novel hair dye composition having excellent dyeing properties and fastness, and further having a good feel after hair dyeing. It was aimed at.

[0004]

Means for Solving the Problems The present inventors have conducted intensive studies for this purpose, and as a result, by using a specific compounding component in combination with a water-soluble acid dye,
The present inventors have found that a hair dye composition having excellent dyeing properties and fastness and a good feel after hair dyeing can be obtained, thereby completing the present invention.

That is, the present invention provides a water-soluble acid dye A,
One or more water-soluble polymers B selected from an amphoteric polymer and a cationized polymer having a cationic charge and having a nitrogen content of 0.5 to 6.0% in solids, an iron compound C, and an organic solvent D And water E.
